The JIH 7 Pieces Aquarium Fish Tank Decorations Decor Set is a great way to add some style and color to your fish tank. This set includes two kinds of decorations: a resin cave rock and six plastic plants. The plastic plants are soft and have no sharp edges, so they won’t hurt your fish. The rock adds a natural element to your aquarium landscape. Made of resin, it has a realistic texture and does not smell. It’s safe for both freshwater and saltwater environments.
